Source: Melexis Interior lighting is interesting for carmakers and customers like never before. Consequently there is a growing trend towards a multi-functional and increasing complex dynamic lighting in the vehicles. Once smart lighting effects become specified for both styling and communication purposes, certain technical challenges arise. Notably, the capabilities of the current CAN and LIN communication protocols are insufficient. CAN is the Controller Area Network; the bus that allows components in an automobile to talk to each other seamlessly. LIN is the Local Interconnect Network; a supplement to CAN which allows for further expansion to peripheral devices. Tomorrow’s cars are likely to contain too many LEDs changing color too rapidly and too frequently for the current CAN and LIN technologies to control efficiently. The latest CAN protocol – CAN-FD – has sufficient bandwidth, but because of its architecture and requirements it is too expensive from a Bill of Materials point of view and too limited in regard to the number of possible connected LED drivers. The communication speed and architecture of LIN makes it a feasible solution for slow animations, but not for high-speed applications. In parallel, the number of RGB-LEDs is increasing, making system integration even more complex, especially when different color sensitivities need to be adjusted separately. At the same time, OEMs do not wish to limit such exciting new features to their high-end cars, and so are looking for high performance at a low cost. Further challenges include: ensuring the necessary flexibility in the car architecture for smart lighting without reprogramming the body control module; managing safety-critical applications; ensuring overall system EMC and ESD robustness in such a harsh environment; and fulfilling space requirements to fit smart lighting in any location within the car. The Melexis solution for smart automotive lighting

#Melexis launched the #MLX81116 a multichannel RGB-LED driver the first device to support the MeLiBu™ a high- speed communication interface enabling #automotive manufacturers to provide enhanced features for #animated #lighting functions. The #MeLiBu™ communication interface is working with the proven CAN-FD physical layer, which ensures robustness, reliability, and high speed (up to 2 Mbit); features that are key requirements for today’s car manufacturers. Meeting automotive ISO 26262 functional safety requirements up to safety integrity level B (ASIL B).

Dear Community, in this COVID19 challenging times a lot is changing, but we all are on the way to handle this pandemic situation. To join virtual or hybrid events are going to be the new normal. The event “Sensor im Automobil” is a hybrid conference focusing on #automotive manufacturers, #sensor suppliers and research institutions to discuss innovative sensor principles under application-related focus. In addition optimizing well-known sensor principles, new sensor systems are becoming increasingly important for generating additional information for the #ADAS-Systems. Get an overview of the most important trends in sensor technology. I would like dive your attention to an presentation from #Melexis of an 3D #Time-of-Flight-Sensor: “Miniaturisierte 3D Time-of-Flight-Kamera zur Innenraumüberwachung und Gestensteuerung im Automotive” Agenda: https://sensoren-im-automobil.de/programm-2020/ Or if you have no time for the conference visit the Melexis Homepage directly https://www.melexis.com/en/news/2018/13nov2018-qvga-tof-chipset-incabin-monitoring-systems https://www.melexis.com/en/news/2017/20nov2017-tofmotion---melexis Best regards, Social.Media@Roland-Steger.de

Dear Community, as a Technology Scout, I would like to drive your attention to a newly released device from #Melexis. This device is used for dynamic ambient interior lighting with #RGB-LEDs. Were speed, accuracy and robustness matters. It's not only the colour mixing with an integrated temperature compensation, it is the accuracy of < 1% delta UV, the supply range, fully diagnosable (Short circuit, broken line, threshold monitor), #ASIL B classification QFN4x4 package, 24 pins. You can drive more the 250 RGB-LED’s on real bus without any delay.

Unsere Vorbereitungen für die #Swiss_Medtech_Day laufen auf Hochtouren. Die Veranstaltung findet am Montag, 21. September 2020 von 08:30 - 17:00h in CH- Bern statt. Die Firma #Microdul AG stellt dort High-Tech im Bereich von #aktiven #Implantaten der Klasse 3. Wenn sie mehr über aktive #Implantate wissen möchten besuchen Sie meine Webseite: https://www.roland-steger.de/aktive-implantate

#Elektronisches_Türschloss Sie können den Energieaufwand von elektronischen Schließsystemen reduzieren, indem sie nur die Bereiche der Elektronik einschaltet, die für die Funktion gerade benötigt werden. Denkbar ist auch der Einsatz von „#Energy-Harvesting“ bei dem effizientes #Power-Management gefragt Value Proposition: - Energie sparen - Aufwachen durch Berührung oder zeitlich gesteuert - Power Management für Energy Harvesting - Kein Batteriewechsel mehr ? - Zeitstempel (Real Time Clock) - Kleinste Verpackungen (z.B. Chip Scale Package) Mehr Info zum #Elektronisches_Türschloss - #Elektronisches_Schließsystem unter: https://www.roland-steger.de/elektronisches-t%C3%BCrschloss

Eingangsgrößen für den Harvester könnten sein: Kinetische-, Thermische- Strahlungs- Energie, Federmasse- Systeme, Linearbewegung, Rotationsbewegung, Schock und Stöße z.B beim Gehen, Fahrradfahren, Schuhsole, usw. Die verwendeten Powermanager müssen mit einem hohen Wirkungsgrad arbeiten bzw. intelligent und stromsparend gesteuert werden. Charge Pump DC/DC Wandler Optimierte Verfahren bei Piezo Anwendungen => hoher Wirkungsgrad Stromsparende Timer- Funktionen Geringe Versorgungsspannungen Bei Energy Harvesting Applikation genügt es nicht, die Einzelkomponenten zu betrachten. Entscheidend ist hier gesamtheitliche Betrachtung der Applikation. Zum Beispiel: Was für Anforderungen stellt meine Sensor (Energieverbrauch) Was kann meine Energy Harvesting Quelle an Energy wann liefern Wie lange muss bzw. kann die Energie gespeichert werden Was muss wie oft gemessen werden Wie sollen die Daten übertragen werden (BLE, ZigBee, Lora, usw,..) Wann und wie oft soll eine Übertragung stattfinden Was ist der Energiebedarf während eines Updates des Sensors Was ist der Energiebedarf während einer Sonderfunktion Haben Sie Fragen zu einer unserer Kernkompetenz dann freuen wir uns über Ihre Kontaktaufnahme.
